# Description

This enables "multidicts". They are a different implementation of the Python `dict` type, indistinguishable for the normal user (when using multidicts, the normal implementation is not used at all). The flexibility of multidicts is used by a couple of other, even more advanced object implementations.

See the description in Standard Interpreter Optimizations for more details.
